To all whom t may concern."

Be it known that I, CHARLES M. REYNARD,

g a citizen of the United States, and resident of McKeesport, in thecounty of Allegheny and State of Pennsylvania, have invented a new anduseful improvement in Apparatus for Cleaning Tin Plates; and 1 do herebydeclare the following to be a full, clear, and exact descriptionthereof.

My invention relates to apparatus for cleaning tin-plates.

ln the manufacture of tin-plates, the sheets are passed from thetinning-pot where they receive their coating of tin to cleaningapparatus to remove the oil and the dirt mixed with the same, which mayadhere to the plate as it comes up through the palm oil which covers thetin in the tinning pots. 1n order to remove this' oil or grease theplates are passed through rolls which revolve in a suitable receptaclecontaining sawf dust, bran or other mlxture which wlll remove this oilor grease as the plates pass through it. i

rlPhe object of the present invention is to provide apparatus of thischaracter in which the saw-dust, bran or other material, which iscarried out of the receptacle by the movement of the plates through thebody of material, is discharged into a suitable receptacle below, sothat it may be conveyed upwardly and discharged again into thereceptacle, by being evenly distributed across the rolls containedtherein, and the invention comprises the novel features hereinafter setforth and claimed.

ln the drawings, Figure l is an end view' of my improved apparatus, andFig. 2 is a longitudinal sectional View.

The numeral 2 designates a suitable stand or frame which supports the-box or receptacle 3 containing the bran, saw-dust or other mixture, 4f,for cleaning the sheets. rllhis frame also forms the support for thedriving mechanism for driving the rolls and the conveyers. rl[`hisdriving mechanism consists of the pulley 5 whichis'mounted on the shaft6 journaled in bearings in the bracket 7 and the stand or frame 2.Rotary movement is imparted to the pulley 5 by means of a belt leadingfrom a suitable motor or engine. The shaft 6 has the pinion 8 whichmeshes with the gear-wheel 9 on the stub-shaft 10. A pinion 11 on thestub-shaft 10 communicates rotary movement to a train lof gears 12-rllhe front wall 15 of the box 3 has the slot 16 y for the entrance ofthe plates to be passed through the rolls. The bottom plate 17 of thebox 3 is removable, being arranged to slide in guides and is providedwith the handle 18 by means of which said bottom may be inserted orwithdrawn.

The frame 2 contains the receptacle 19 with the inclined walls 20, andat the bottom of said receptacle, extending transversely of the frame 2is the spiral conveyer 21 carried by the shaft 22. This shaft 22 isjournaled in suitable bearings in the frame 2 and at one end of saidshaft is the sprocket wheel 23. A chain 24 engages said sprocket wheel,said chain leading from the sprocket wheel 25 on the shaft 6. ln ,thisway rotary movement is imparted to the spiral conveyer 21. The spiralconveyor 21 extends out into the inclined passage 26 which communicateswith the upwardly extending passages 27. A bevel pinion 28 on the shaft22 meshes with a bevel pinion 29 on the shaft 30 which carries thespiral conveyer 31 working in the passage 27. rfhe upper end of thepassage 27 communicates with the curved passageway 32 which is formed ofan elbow section 33 connected to the passage 27 by the collar 34 whichis adapted to turn on the upper end of the passageway 27.

The curved passageway 32 discharges into the hopper member 35 extendingtransversely of the frame 2, said hopper member being supported on theswinging bracket 36, which is hinged to the box 3 atl 37. The bottom ofthe hopper 35 is provided with the longitudinally extending slot oropening 38. A slidable cover 39 controls the size of the opening 38,said cover being held in any desired position by means of the set-screws40. Contained within the hopper 35 is the spiral conveyer 41 mounted onthe shaft 42. lf his shaft 42 is providedl with the sprocket wheel 43,and achain 44 connects said sprocket wheel up with the sprocket wheel 45on the shaft 46, which is driven by the train of gearing 12.

The plates to be cleaned, as they come from the tinning-pots, 'areinserted into the opening 16 at the front end of the box 3, and aretaken up by the first pair of rolls, and are fed forward through thesucceeding rolls passing through the bran', saw-dust or other cleaningmaterial 4, and as the plates pass through and over the end wall 14, a

certain amount of cleaning material will be carried over with .saidplate, and this will fall down into the'receptacle 19 and into positionto be operated on by the spiral conveyer 21. This conveyer 21 conveysthis cleaning material into the inclined passage 26, where it is forcedalonginto the passage 27 to be taken up by the spiral conveyer 31 anddischarged at the upper end thereof into the passage 32, whence it isdischarged into the hopper 35. The spiral conveyer 31 in said hoppermoves it along said hopper until it reaches the opening 38, whence it isdischarged into the box 3 at a point adjacent to the first pair of rolls13. By having the inclined passage 26, there is no clogging up of thematerial but it is forced up the inclined passage 26 to be engaged bythe spiral conveyer 31 in the passage 27. In this manner I provide forthe recovery of the cleaning material which is carried from the cleaningbox by the plates in their passage through the rolls, and this cleaningmaterial is conveyed rapidly back to the point Where it is dischargedinto the cleaning box, so that the cleaning box is constantly beingreplenished and' interruption in the work due to the replenishing of thecleaning box is avoided, while at `the same time cleaning material is soevenly distributed in the box as to prevent the collection of cleaningmaterial in piles at any one po1nt.-

When the cleaning material has become saturated with oil and grease, andit is nec# essary to remove such cleaning material and introduce a cleansupply into the box, the sliding bottom 17 is withdrawn, which allowsthe material to drop into the recepta-4 cle 19 and it is conveyed off bythe `spiral conveyers in the manner above described, but in order not toreturn it again to the hopper 35 the elbow 33 is turned around inposition to discharge this material in another' direction, and when allthe material has been removed in this way, the slide 17 is inserted. Thebracket 36 is then swung back together with the hopper 35 which giveseasy access to the boxfor the introduction of a new lot of cleaningmaterial.

What I claim is:

1. In apparatus for cleaning tin plates, the combination with asuitableframe, of a receptacle for containing the cleaning material, powerdriven rolls mounted in said receptacle, a second receptacle below saidfirst named receptacle, a hopper member above said first namedreceptacle having an elongated opening extending across said first namedreceptacle, a conveyer in said hopper member, and means for conveyingthe material from said second named receptacle to said hopper member.
